WILLIAM KRUTZSGH, OF DAYTON, OHIO, ASSIGNOR TO THE BUCKEYE IRON ANDBRASS WORKS, OF SAME PLACE.

OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 334,710, dated January19, 1886.

(No model.)

To all whom it may concern:

Be it known that I, WVILLIAM KRUTZSOH, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented new and useful Improvements in Oil-Cups, of which the followingis a specification.

My invention relates to an improved stopper for oil-cups or lubricatingdevices; and it consists of an oil-cup having a filling-orifice at oneend, and inclosing a spring-actuated stopper which presses outwardwithin the filling-orifice, thereby securely closing the cup, butallowing the said filling'orifioe to be un- [5 covered by pressing thespring-stopper inward and to one side.

The invention is illustrated in the annexed drawings, in which Figure 1is a vertical section of my improved lubricating-cup on the line 00 x ofFig. 4. Fig. 2 is a sectional detail view taken on the line y g of Fig.4, the iilling-orifice being shown closed. Fig. 3 is a side elevation ofthe cup, partly in section, on the line pg of Fig. 4, thefilling-orifice being shown open with the stopper pressed inward and toone side. Fig. i is a plan view of the oil-cup.

Referring to the drawings, A represents a cylinder of glass or othermaterial, preferably transparent. To the upper end of this cylinder isattached a cap, 13, and the lower end is closed by a plate, (J, havingon its outer face a threaded tubular shank, O, by which the cup isconnected with the mechanism to be lobricated. On the inner face of thisbottom plate, 0, is formed a tubular stem, D, which passes through theoil-cup and its cap B, and is secured thereto by a nut, E, on the outerside of said cap.

F is the feed-rod, which works in the tubular stem D and controls theflow of oil from the cup through an outlet, H, at the lower end of saidstem. The feed-rod is provided with a milled head, R, and its lower endis threaded 4 5 and grooved at H, so that by means of its head B it maybe turned sufficiently to cause said groove H to register with theoil-outlet H and enable the oil to be fed from the cup. By turning thefeed-rod F in the opposite direction the flow of oil will be arrested.

G G represent packing-rings, of cork or other material, placed at eachend of the cylinder. The cap Bhasafilling-orifice,l,through which thecup is supplied with oil. This filling-orifice is closed by aspring-actuated stopper, J, which is arranged Within the oil-cup in sucha manner as to be pressed inward and away from the opening I when it isdesired to replenish the cup. The stopper J is formed with a tubularportion. K, which fits over a collar, M, on a rod, L, the lower end ofwhich is seated in a socket, N. on the inner side of i the bottom plate,0. The upper end of the stopper is provided internally with aguidesocket, Q, which receives the upper end of the rod L when thestopper is pressed down. Within the tubular portion K of the stopper andsurrounding the rod L is a spirally-coiled spring, P, one end of whichrests on the collar M, while the other end bears against a 7c shoulder,T, at the upper socketed end of the stopper. The spring 1? is thusinclosed in the stopper and is not liable to become broken ordisarranged. The upper end of the stopper is providedwith a button orfinger-piece, O, which projects laterally from a neck, S, that connectswith the stopper and projects through the filling-orifice. When thestopper J and its rod L are in line with the filling-0rifice I, thestopper will be supported and pressed 8o outward by the spring P so asto enter the orifice I from its inner side, and thus securely close thecup. It will be observed that the edge of the opening I is beveleddownward to correspond with and fit a similar beveled surface on theexterior of the stopper. When the stopper is in place, therefore, asshown in Figs. 1 and 2, it completely plugs the orifice I andeffectually prevents the escape of oil or the entrance of dirt or otherforeign matter. By pressing the button or finger-piece 0 downward and toone side the neck S will be carried down through the opening I until theupper end of the stopper engages the under side of the cap B at the sideof the opening, as shown in Fig. 3, and thus uncovers said opening orfilling-orifice so as to permit filling or refilling the cup. While thestopper is thus engaged with the cap the filling-orifice will re- I mainopen without any necessity of holding the 1 button or finger-piece O.

In order to close the oil-cup it is only necessary to give the button 0a slight push, when the stopper J will immediately spring intoengagement with the filling orifice.

A spring-actuated stopper of the form described is adapted to securelyclose the oileup at all times, and is not liable to become disarrangedor jarred out of place. This construction also renders it impossible forthe spout of the filling-can to enter the filling-orifice I so far as toobstruct the free exit of the displaced air.

What I claim as my invention is- 1. In an oil-cup, the combination, witha cap having a fillingorifice, of an internal spring-actuated stopperhaving a finger-piece that projects through said filling-orifice,substantially as described.

2. In an oil-cup, the combination, with a cap having a filling-orifice,ofa laterally-movable spring-actuated stopper inclosed in said cup, andprovided with a finger-piece projecting through said filling-orifice,and a movable rod for supporting said stopper, substantially asdescribed.

3. In an oilcnp, the combination of a cap having a filling-orifice,aspring-actuated slopper inelosed in the oil-cup and having afinger-piece and a connecting-neck projecting through saidfilling-orifice, and a rod for supporting and guiding the stopper, saidrod being seated at the bottom of the cup and having a collar forsupporting the stopper-spring, substantially as described.

4. In an oil-cup, the combination of a cap having a filling-orifice, abottom plate provided with a socket, a tubular stopper arranged Withinthe oil-cup and having a fingerpieee projecting through thefilling-orifice, a movable rod seated in the socket of the bottom plateand having a collar, and a spring inelosed in the stopper andsurrounding the upper end of said rod, substantially as described.

5. In an oil-cup, the combination of the cylinder A, the cap 13, havinga filling-orifice, I, the bottom plate, 0, provided with socket N, thetubular stopper J, the rod L, having collar )I, and the spring P,substantially as described.

In testimony \vhereofI affix my signature in presence of witnesses.
